Carbide Inserts for Foundation Drilling Tools and Mining Tools including Roof Bit inserts, conical insets, P conical inserts, conical inserts, Narrow Bottom inserts, coal mining Tips, rectangle tips, flat bit inserts, Flat top insert and etc. Solid Carbide Insert Drill Bits For Foundation Drilling Tools And Mining Tools
Button drill bits are made by high quality alloy steel bar and tungsten carbides. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks. Besides, we can design customized thread button drill bits according to different drilling application, and custom drill bits are applicable to drill soft rock, loose-medium rock and hard rock.
Application of Drill bits inserts tungsten carbide buttons
Tungsten carbide drill bits are widely used in mining, sand,cement,metallurgy and hydro-power engineering industries.
Our advantages:
1. High stability, long life circle
2. Good abrasive and corrosion resistance
3. High quality and high hardness
4. Purity without recycled material
5. Fast delivery
6. Produced according to your requirements
7. Various type, blanks and polished (precision machined) mining bits.
8. OEM accepted
